Okay, another newbie question for all you experienced moms out there. I'm wanting to pick up a breast pump before baby arrives, just in case I need it for any reason. I figure I can always sell it if it turns out I don't need it. But I may be going back to work at 4 months and my DH would be staying home, in which case I'll need a pump by then anyways.
So, my question is this - what features did you find particularly useful in a breast pump? What did you hate, and what could you not live without? What brand do you prefer and why? My SIL has an Ameda pump and loves it. I see a lot of ads for Medela pumps in my area. Is one better than the other or is it mostly personal preference?
Lastly, would you consider buying a second hand breast pump? If so, what would you be careful to watch for in a second hand pump? If not, what is the reason?
